84 Mr. M. Burr — Notes on the Forficulaiia. 



Feet light testaceous, short, the femora rather strongly 

 compressed. 



Abdomen depressed, slightly dilated posteriorly. Tiie 

 segments, except the last, are all finely granulated, each 

 segment being also slightly broader than the previous one ; 

 the tubercle on the second segment is very distinct, black, 

 the tubercle on the third segment is considerably larger and 

 black ; these two segments are much darker than the re- 

 mainder, and the part round the tubercles also is black ; the 

 last dorsal segment is very large, square, light testaceous, 

 smooth and shining ; at each angle on the posterior margin 

 above the insertion of the forceps is a large round tubercle, 

 slightly furrowed in the middle, giving the appearance of a 

 double tubercle. The underside of the abdomen is much 

 paler than the dorsal side and is entirely granulated. The 

 penultimate segment is very large, only leaving the ultimate 

 segment visible at the extreme posterior corners. The poste- 

 rior margin of the last dorsal segment has an impression in 

 the middle. 



Forceps : these are very long and slender, almost as long 

 as the body. At the base they slightly diverge at first, then 

 gradually point inwards, to meet and cross at the apex. At 

 the base they are triquetric and armed with a small conical 

 tooth on the inner margin, just at the pygidium ; there is a 

 second, much stouter tooth halfway down on the inner margin ; 

 the part between these teeth is finely crenulated. The colour 

 of the forceps is clear testaceous, on the underside they are 

 flattened. 



Pygidium short, rectangular, very broad, not toothed or 

 emarginate, the hinder border straight and simple ; the angles 

 are sharp j in the middle on the upperside it is slightly 

 bi- impressed. 



Patria. British East Africa, Nairobi, 5500 feet ; Kikuyu 

 Country, July 1899 (//. J. Mackinder & G. B. Hamburg). 



Type in Mus. Hope, Oxford. 



In the form of the forceps, lengthening of the body, and 

 largeness of the abdominal tubercles this species recalls certain 

 species of Forcipula ; but the lobed second tarsal segment 

 definitely shows that it cannot be related to that genus. 



I have great pleasure in dedicating it to Mr. H. S. Mackinder, 

 the eminent geographer, who discovered it during the recent 

 expedition to Mount Kenia. 



For the drawings of this species I am indebted to my 

 friend Mr. E. H. J. Schuster, F.Z.S.
